jQuery是一个著名的JavaScript库，它提供了简洁而强大的功能，用来简化JavaScript编程。当引入jQuery到你的网页项目中时，你需要在HTML文件中添加以下代码来引入必须的包：

<!DOCTYPE html>
<html>
<head>
    <title>我的网页</title>
    <!-- 引入jQuery -->
    <script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
</head>
<body>
    <h1>欢迎来到我的网页</h1>
    <p>这是一个示例网页</p>
    <script>
        // 这里可以写你的JavaScript代码，使用jQuery的功能
        // 例如：
        $(document).ready(function(){
            alert("网页加载完成");
        });
    </script>
</body>
</html>

在上面的代码中，第6行引入了jQuery库，你可以通过将这段代码粘贴到你的HTML文件中来引入jQuery库。之后，你就可以在页面中使用jQuery的功能来简化DOM操作、事件处理、动画效果等操作。jQuery的强大功能和简洁语法使得前端开发变得更加高效和便捷。
